I would strongly advise against leaving a terminal in the field in a tamper state, but if it is your dev terminal, then the ONLY difference is that you will have to press clear during boot up and then everything else should be the same. The good news is that (at least as far as I'm aware) there is no problem with leaving the terminal in this 'tamper' state from a functionality stand point. When I get a tamper message on one of my terminals, I have to send it to them and they deal with it for me.

As such, the repair people are instructed not to give this software out. By requiring people to pay a hefty tuition and take the class, they severely limit the probability that this will occur. If you think about it, this does make some sense-if they were to put the 'tamper clear' download 'in the wild', then someone could easily tamper with a terminal and then just clear the message when they were done. If you haven't taken the class, VeriFone won't give it to you.

The company has paid for the people there to take a class from VeriFone on how to repair the terminals and as part of the tuition, they get access to some special software like the tamper clear file. We actually go through enough terminals at my company that we have a terminal repair department. What makes it hard is GETTING this special file to download. Well, it's actually very simple to do, you just have to download some special file to the terminal's group 1.

So, now to your question-how do I clear it? In this case, you can clear the message and it will not (necessarily) come back right away. It is possible (though less likely) to trip one of the pressure points by simply dropping the terminal or doing something similar-especially if there is a loose screw somewhere. I'm convinced they made this as complicated as possible so that you would be almost forced into sending the terminal in for repairs. In order to keep it from coming back, you will need a new battery and that's actually a pretty involved process-you have to take the terminal all apart, desolder the battery from the main board, and then solder a new one on. When this is the case, you can clear the tamper message, but as soon as you unplug the power, the message will just come right back. In my experience, the dead battery is the most common reason a terminal would go into this tamper state. If the power is unplugged and the battery dies, then the terminal is unable to guarantee that it has not been tampered with, so it alerts you that it has been, just for good measure. In order for the terminal to be able to detect an intrusion, even when the power is unplugged, it has a battery (it also supplies power for the internal clock, but that's a different topic.). This is not only a good feature (there have been merchants that were burned by not having this in the past), but necessary for PCI compliance.

If any of these pressure points is tripped, the terminal goes into a 'Tamper' state to alert the next user that there may be something wrong.

The purpose of these is to be able to tell if someone is trying to open the terminal up to install a card skimmer or other nefarious device that could compromise security. Inside the terminal there are something like 5 pressure points. ORIGINAL ANSWER:įirst you need to understand where this error came from.

Keunhee han posted an answer that says to go to the 'IPP KEY LOAD' in system mode and then press F1.
